The Libertines star Pete Doherty is preparing to sell off his unusual rock 'n' roll memorabilia, including cigarette butts smoked by late pal Amy Winehouse and his ex-girlfriend Kate Moss.

The British rocker opens up about his plans in the latest issue of NME magazine, revealing he wants to set up a market stall in Camden, London - the borough where Winehouse lived before her death in 2011 - for the sale.

Doherty says, "I've got fag butts that belong to Bobby Gillespie, Kate Moss and Amy Winehouse, and I've got Christmas paper that (retired soccer goalkeeper) Steve Ogrizovic sent to the guy from Black Sabbath. All kinds of s**t basically."
